--- Comment #9 from Richard Biener <rguenth at gcc dot gnu.org> ---
Complete peeling is known of not eliminating all unreachable code which is why
-Warray-bounds now runs _before_ unrolling only. Note it's practically
impossible to cover all cases in peeling but there's some that could
(identified in some old PR I can't find right now).

Certainly. So ISTM this is punt to gcc-11 (and likely beyond) and hope that
one day we can do better at determining some of the unrolled iterations can't
actually happen at runtime and can be removed.
